Common Issues
John Deere 4720 tractors are reliable, but they have their problems. Owners often face recurring issues with the engine and transmission. Understanding these problems can save time and money.
Engine Problems
The engine is the heart of the tractor. Some common engine issues include overheating and hard starting. Overheating can stem from a clogged radiator or low coolant levels. Regular checks can help prevent this.
Hard starting is another problem. This can be due to a weak battery or faulty fuel system. Cleaning the fuel injectors and checking the battery can solve this. Routine maintenance is crucial for engine health.
Transmission Troubles
Transmission problems are frustrating for John Deere 4720 owners. Slipping gears and delayed shifts are common complaints. Slipping gears can indicate worn-out transmission fluid or damaged gears.
Delayed shifts often mean issues with the clutch or transmission control module. Regularly changing transmission fluid and inspecting the clutch can help. These steps ensure smooth operation and longevity.
Hydraulic Failures
Hydraulic failures can be a significant concern for John Deere 4720 owners. These issues not only affect the performance of your tractor but can also lead to costly repairs and downtime. Understanding common hydraulic failures, such as leaks and pressure loss, can help you address these problems more effectively.
Leaks
Hydraulic leaks are a common problem in the John Deere 4720. One of the first signs of a leak is fluid on the ground where your tractor is parked. This can quickly lead to a drop in hydraulic fluid levels, affecting the overall performance of the machine.
Inspect all hoses and fittings regularly. Look for signs of wear and tear, as well as any visible cracks or breaks. Replacing a damaged hose early can prevent bigger issues down the line.
Don’t forget to check the hydraulic fluid reservoir. Ensure it’s always at the recommended level. Low fluid can cause the system to overheat, leading to more leaks and further damage.
Pressure Loss
Pressure loss in the hydraulic system is another issue you might face with your John Deere 4720. When the hydraulic system loses pressure, it can struggle to lift or move attachments, impacting the efficiency of your work.
Regularly check the hydraulic pump and valves. If you notice a drop in pressure, it could be due to a failing pump or a malfunctioning valve. Address these issues promptly to maintain your tractor’s performance.
Another factor to consider is the hydraulic fluid itself. Contaminated or old fluid can cause pressure problems. Make sure to follow the manufacturer’s recommendations for fluid type and change intervals.

Electrical Malfunctions
Electrical malfunctions in the John Deere 4720 can cause significant downtime. These issues often stem from problems with the battery and wiring. Understanding these common issues can help you maintain your tractor better.
Battery Issues
One common electrical problem is battery failure. The battery may not hold a charge. This could result from age or improper maintenance. Regular checks can prevent this issue.
Corrosion on battery terminals is another problem. It can disrupt the connection. Cleaning the terminals regularly can help maintain a good connection. Always use protective gear when handling the battery.
Wiring Problems
Wiring issues can also lead to electrical malfunctions. Damaged wires can cause short circuits. Inspecting the wiring system regularly can help you spot problems early.
Loose connections are another common issue. They can cause intermittent electrical failures. Tightening all connections periodically can help maintain the tractor’s performance. Look for signs of wear and tear on the wires.
Rodents can chew on the wiring. This can lead to serious electrical faults. Using rodent repellents can prevent such damage.
Overheating
Overheating is a common issue with the John Deere 4720 tractor. It can lead to engine damage if not addressed promptly. Knowing the causes of overheating helps in finding solutions. Let’s explore some key factors causing overheating.
Cooling System
The cooling system is crucial for maintaining the engine’s temperature. If it fails, the engine can overheat quickly. Issues in the cooling system can include leaks, blockages, or a malfunctioning radiator. Regular maintenance of the cooling system helps prevent these problems.
Check the radiator for dirt or debris. Clean it thoroughly to ensure proper airflow. Inspect hoses for any leaks or damage. Replace them if necessary. A clean and well-maintained cooling system keeps the engine cool and running efficiently.
Thermostat Issues
The thermostat regulates the engine’s temperature. If it is faulty, it can cause overheating. A stuck thermostat can prevent coolant from flowing properly. This leads to excessive heat buildup in the engine.
To fix thermostat issues, replace the faulty thermostat. Ensure it is installed correctly. Regular checks and timely replacement of the thermostat are essential. This prevents overheating and keeps the engine in good condition.
John Deere 4720 Problems [Here is the Fuel System Problems]
Fuel system problems can be particularly frustrating for John Deere 4720 owners. They can disrupt your work and lead to costly repairs. Understanding the common issues can help you address them swiftly and minimize downtime.
Injector Issues
One common problem with the John Deere 4720 is injector issues. Injectors are crucial for delivering the right amount of fuel into the engine. When they malfunction, your tractor may experience poor performance.
You might notice black smoke from the exhaust or a significant drop in fuel efficiency. These symptoms indicate that the injectors are not working correctly. Regular maintenance and timely replacement can save you from bigger headaches down the road.
Have you ever had to deal with injector issues? It can be a real challenge, especially during peak farming season. Keeping an eye on the injectors and ensuring they are clean can prevent many problems.
Fuel Pump Failures
Fuel pump failures are another common issue with the John Deere 4720. The fuel pump is responsible for delivering fuel from the tank to the engine. When it fails, your tractor may not start or could stall unexpectedly.
Imagine trying to finish a crucial task, and your tractor just stops. This can be incredibly frustrating. Regularly checking the fuel pump and ensuring it’s in good condition can help avoid such scenarios.
A simple tip: listen for unusual noises from the fuel pump. Strange sounds can be an early indicator of a failing pump. Addressing these issues early can save you time and money.

Steering Difficulties
The John Deere 4720 is a reliable tractor, but like any piece of machinery, it isn’t without its issues. One common problem that many owners face is steering difficulties. This can be a significant hindrance, especially when precision is crucial for your tasks. Let’s delve into some specific steering problems you might encounter with your John Deere 4720 and how to address them.
Power Steering Issues
Power steering is a vital feature that makes maneuvering your tractor easier. However, when it fails, you might notice your steering becoming stiff or unresponsive. This can be due to low hydraulic fluid levels or a malfunctioning power steering pump.
Make sure to regularly check your hydraulic fluid levels. Low fluid can cause the steering to feel heavy. Topping up the fluid can often resolve the issue.
If the fluid level is adequate, the problem might lie with the power steering pump. Replacing the pump can be a bit costly, but it’s essential for maintaining smooth steering.
Steering Column Problems
The steering column is another component that can cause trouble. Issues here might include unusual noises, excessive play in the wheel, or difficulty in turning. These problems can stem from worn-out bearings or loose connections.
Check for any loose bolts or connections in the steering column. Tightening them can sometimes solve the issue. If you hear grinding or clicking noises, the bearings might be worn out and need replacement.
